Given numbers are 417, 208, 818, 401
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(417, 208) = 86736
GCD(417, 208) = ( 417 x 208 ) / 86736
= 417 / 208
= 417
Step2:
LCM(1, 818) = 818
GCD(1, 818) = ( 1 x 818 ) / 818
= 1 / 818
= 1
Step3:
LCM(1, 401) = 401
GCD(1, 401) = ( 1 x 401 ) / 401
= 1 / 401
= 1
So, Greatest Common Divisor of 417, 208, 818, 401 is 1
